Crowds gather in Tehran to mourn supreme leader Khamenei

Large crowds of Iranian people gathered at Tehran's Enqelab Square on Sunday morning to mourn Supreme Leader Ayatollah Ali Khamenei, who was killed in U.S.-Israeli attacks on Saturday.

The Iranian government announced a 40-day mourning period after the country's state media confirmed the leader's death on Sunday.

Several Iranian senior officials, including Chief of Staff of the Iranian Armed Forces Abdolrahim Mousavi, Defense Minister Aziz Nasirzadeh, Secretary of the Defense Council Ali Shamkhani, and Mohammad Pakpour, chief commander of the Islamic Revolutionary Guard Corps, were also killed in the strike.

The mourners, some crying, were in grief and rage.

"We came here to show that we are more united than ever. We will always be there for our revolution," said one of the mourners.

"They have assassinated our leader, but they should know that we will get our revenge," said another mourner.

"Let them not think that by targeting our supreme leader, they can come into our country. We will not give even a single centimeter of our country," said a female mourner.

On Saturday morning, Israel and the United States launched joint attacks on Tehran and several other Iranian cities, including Tabriz, Qom, Isfahan, Kermanshah, and Karaj. Iran responded with missile and drone strikes targeting Israel and U.S. bases across the region.
